Consider beam of rectangular section, simply supported over a span of L carrying an UDL of w. if the beam is subjected to the prestressing force of P.

a). Draw a sketch of the stresses applied to the section and use the principle of superposition to combine the stresses. consider the prestressing force is applied at zero eccentricity (e=0)

b) Determine the collapse load, w_u when the prestressing force is applied at zero eccentricity. (e=0)

c) Provide an effective solution to double the load-carrying capacity of the concrete beam, without altering the dimensions or increasing the concrete strength.
